Google "Bubba Stick"- - - - -they've got a brass or chrome horse collar hame knob for a handle. I buy the vintage hames on Ebay and make my own shafts from 1" diameter hardwood dowels. The one I'm working on now has a stack of drilled-out 2" wooden balls for most of the length. The hollow brass hame has a little over a pound of #8 birdshot poured into it, then it's filled with Great Stuff expanding foam.
